Unpublished letter to Julie Mangin (1791-ap.1855), mother of the famous scientific popularizer. He talks about his health, which was poor on his return from London and his stay in Calais. He thanks her for the translation of a brochure by Harys (?) and is proud to own a translation by Mme Mangin. He saw his son, Amédée, who honors his parents. He will spend the winter in Marseille and go to London in the spring, when he hopes to see the progress of his daughter, Clara Mangin, on the piano. Paganini's secretary was Georges Harrys (or Harris), son of a Hanover rabbi. Julie Mangin was of German origin. The letter, weakened by the original folds (closed mail with address on the back), has been lined with Japanese paper.
